It takes just 30 seconds, an internet connection and your name before you could be looking at extra cash for Christmas.
You may not even realise you have lost bank accounts, shares or life insurance policies, but A Current Affair shows you how to get what's yours.
It means you could be sharing in the $677 million the Australian Securities and Investments Commission is trying to hand back.
To see if you are entitled to any extra cash, visit www.moneysmart.gov.au.
If you have problems getting on to the website to search for unclaimed money, it's because thousands of other people are trying to search at the same time.
Don't worry, your money will still be there but we suggest waiting a bit and trying again later.
